Mind you, those are micro-drones with a wingspan under 12 inches, not drones capable of delivering your new microwave or big box of unnecessary things.

Something that has become increasingly clear is that planners, engineers, regulators, and legislators need to think about noise and its consequences when they consider new ideas like drone delivery. Everything is connected, perhaps even more so as we live closer together, and the freedom of individuals, organizations, or commercial operations to do something must be balanced with the rights of those affected so that their lives are not disrupted by this new activity.

And what happens if we fail to consider the impacts of new technologies on others? Imagine walking down a city street with a loud, never-ending buzz hovering over you, as your fellow city denizens anxiously wait for the delivery of their new shiny thing. Jane Jacobs would spin in her grave. One hopes, at least, that your flying car will be sound insulated.
